You may think taking you kids to the local playground to muck around on the swings, slippery dip and monkey bars offers the best exercise but new research shows giving them objects like a bucket, broomsticks or milk crates is a better option. RMIT's Dr Brendon Hyndman spoke to Weekend Breakfast about the findings of his research.

Paracetamol, a common pain reliever considered safe for pregnant women, has for the first time been linked to an increased risk of attention deficit and hyperactivity disorder in children.

Researchers are pointing to paracetamol use as a new potential cause for the worldwide rise in cases of ADHD, a neuro-behavioural condition which has no known cause.

A study published in the Journal of the American Medical Association Pediatrics found women who took paracetamol - also known as acetaminophen - while pregnant, had a 37 per cent higher risk of having a child who would later be diagnosed with hyperkinetic disorder, a severe form of the condition.

Compared to women who did not take paracetamol while pregnant, women who did also had a 29 per cent higher chance of having children who were later prescribed medications for ADHD.

In this episode of The Health Quarter, a Productivity Commission report details a rise in serious mistakes in hospitals, leaps and bounds are made in stem cell research, and a magical form of therapy changes young lives.
